[Y-chromosome microdeletions as a prognostic marker of male infertility]
Abstract:
The results of molecular-genetic study of Y-chromosome microdeletions in men with spermatogenesis failure and in patients with cryptorchism are presented. The molecular-genetic studies of regions AZFa, AZFb, AZFc in STS loci - sY84, sY86, sY127, sY134, sY254, sY255 and SRY gene have been performed. Y-chromosome microdeletions were detected in 13,3% infertile men with spermogram failure. The frequency of genetic (cyto- and molecular) abnormalities among boys with isolated cryptorchism was 4%. The results show the necessity of additional study ofgenetic factors ofcryptorchism development.

Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size. Today,...

X and Y Chromosomes
The germline cells such as egg and sperm cells carry only half the number of chromosomes, i.e., 22 autosomes and one sex chromosome. All eggs have an X chromosome, while sperm cells can carry an X or...
